POULTRY-HOUSE.

Specification of Letters Patent.

Application filed August 31, 1910.

Patented Jan. 24, 1911.

Serial No. 579,869.

To all whom it may concern:

Be it known that I, PAUL KUBEIN, a citizen of the United States, and aresident of Atco, in the county of Camden and State of New Jersey, haveinvented certain new and useful Improvements in Poultry Houses, of whichthe following is a specification.

My invention relates to poultry houses, such as are equipped for housingchickens and other poultry, and the object of my improvements is toprovide a device which is adapted to be operated by the poultry foropening the door of its house, and a further obj eet being a pivotedlever for preventing a slidingly suspended door from opening the houseand supporting a platform on which the poultry w1ll step or alight whendescending from the roost in the morning to cause the lever to releasethe door and to open the house to allow the poultry to escape.

With this and other objects in view, my invention consists in theconstruction, combination and the arrangement of arts, as will behereinafter more fully described and claimed and illustrated in theaccompanying drawing, it being understood that changes in form, size,shape and other minor details may be made within the scope of my claimwithout departing from the spirit or sacrificing any of the advantagesof my invention.

In the accompanying drawing, Figure 1, is a sectional side elevation ofmy poultry house; Fig. 2, is a front elevation thereof, and Fig. 3, is aplan view thereof.

Similar figures refer to similar parts throughout the several views.

A door 5, is free to slide vertically in a recess 4, of the wall 1, alongrooves 7 7, guided by strips 6, 6, covermg its edges 8, 8. The door issuspended from a rope 9, passing over pulley 10, 10, and carrying aweight 11.

Inside the house 2, near the opening 3, of the wall, is mounted brackets12, 12, on which is pivoted a lever 13, provided with a Vertical arm 14and with a horizontal arm 15. The arm 14, is provided with a bracket 16,on which is pivoted a plunger 16', and with a bracket 19, on which ispivoted a rod 19. The plunger 16, is passed through a hole 18, under thestrip 6, and the rod 19 passes through a hole 20 and its projection 22,is provided with a slot 21, for a pm 23.

On the arm 15, is mounted a wooden platform or step 24.

The door 5, is provided with a socket 25, so that when the door ispulled down until the openin 3 is closed, the socket is directly infront of the plunger, and the weight of the arm 14 causes the lever toswing and forces the plunger within the socket and holds the door downover the opening. When a chicken alights orjumps on the platform, itsweight causes the lever to swing and the arm 14 pulls the plunger out ofthe socket. The door is then free to be moved by the weight 11, and itslides up past the opening and the chickens are free to escape.

It will be understood that the door is shut at night after the fowlshave gone into the house, but in the morning the door is automaticallyopened by the fowls as soon as they leave their roosts and jump oralight on the platform or step, which is natural for them to do.

WVhenever it should become necessary to prevent the chickens fromopeningthe door, a pin is slipped in the slot of the rod, which has theeffect of locking the plunger in the socket.

Having thus described my invention,what I claim as new and desire toprotect by Letters Patent, is-

In a chicken house, a wall provided with an opening and recessed aroundsaid opening, strips mounted on the wall forming vertical grooves withthe recess on each side of the opening, a door for closing the openingsuspended from a rope and free to slide in the grooves and along therecess, said door having a socket which is in alinement with a holethrough the recessed portion of the wall when the door covers theopening, a lever inside the house pivoted on a bracket mounted on thewall and provided with a vertical arm and with a horizontal arm, aplunger pivoted on the vertical arm and passing through the hole of therecessed portion of the wall to plunge into the socket when the door ispulled down to cover the opening, a platform mounted on the horizontalarm to receive a weight for causing the vertical arm to pull the plungerout of the socket, a weight suspended from the rope for causing the doorto uncover the opening when the plunger is out of the socket and a rodextending through the door I specification, in the presence of twosubframe plvoted 0n the vertical arm and proscrlblng wltnesses.

vided With a slot for a pin to prevent the plunger from being withdrawnfrom the PAUL 5 socket, substantially as described and for Wit thepurposes set forth. ADAM R. SLOAN,

In testimony whereof I have signed this LUCY SLoAN.
